A. Tsunamis:
Tsunamis usually cause the greatest amount of destruction in comparison to other waves. There are massive waves that can cause the destruction of most ecosystems.
Explanation:
- Tsunamis cause large displacement of the water bodies and are generally known as the killer waves.
- The tidal waves are a regular recurrent shallow body of water and affect the gravitational attraction between the sun and the Sun, Moon and the earth and maybe often referred to as tsunami but do not generate to the small tidal waves  
- The wind-driven waves or the surface waves are those created by the formation of the surface water and them tens to blow away the occurs for the Oceana and are found across the open seas and globally across the coast. As compared to the tsunami that is tectonically produced these are due to the disturbance in the body of the water.

Answer:
most dangerous geologic hazards are earthquakes
Explanation:
most dangerous geologic hazards are earthquakes
because 
we know that Geological hazards occur because of geological processes that is movement in the tectonic plates and the volcanic activity
and due to movement of tectonic plate it generate the earthquake , landslide and volcanic etc
so here earthquake is more danger and hazards because volcanic and landslide most come in hilly area and density of people is more in plane surface as compare to hilly area 
so most dangerous geologic hazards are earthquakes
